  • Studies of Leaching Characteristics of Arsenic and ...

    antimony in the tailings are high especially in the Jinpan Gold Mine No. 3 tailings with the leaching concentration about 1.46 mg/L of arsenic and concentration about 0.075 mg/L of antimony after two months. The concentrations of arsenic and antimony in dissolution liquid from the two old tailings almost did not change with the increase of time.

        Leaching at lower pH values (10 rather than 11) will reduce the solubility of these minerals in a cyanide solution. What Happens to Arsenic during Refractory Process Is it Destroyed. During a refractory treatment process like Albion, the Arsenic precipitates as ferric arsenate and arsenical ferrihydrite.
